in just 30 mins a day.
how much longer will your child’s progress be put on hold?
Endless Waitlists
Stuck on a clinic waitlist for months or even a year? Every day spent waiting is a missed opportunity during your child’s crucial developmental window.
Unclear Progress
Even after starting therapy, the lack of a clear timeline or visible changes at home leaves you feeling anxious and completely frustrated.
High Costs & Burnout
Expensive out-of-pocket costs add up fast. Plus, the constant commuting to appointments leaves both you and your child exhausted.
Is 40 minutes of clinic therapy a week really enough?
Out of 168 hours in a week, those 40 minutes fly by.
To truly unlock their potential, progress can’t pause when they leave the clinic.
🔴 Red slice: Clinic sessions (40 mins)
⚪ Gray area: Time outside the clinic (167 hrs 20 mins)
The ‘Time’ Gap
1-2 clinic sessions a week aren’t enough to build lasting neural pathways. Without active engagement on the other 5 days, your child’s brain misses out on vital daily stimulation.
Missing Daily Reinforcement
Even the best therapy needs daily practice to stick. Consistent repetition at home is what actually wires these new cognitive skills into your child’s daily life.
Speech and social skills can’t grow without a solid “Cognitive Foundation.”
Are you pouring water into a leaky bucket?
If a child struggles to process information (Input), forcing them to speak (Output) will only lead to exhaustion and stalled progress.
Does this sound like your child?
If you check even one of these boxes, right now is the golden window for cognitive training.
Speech & Language Delays
Despite months of therapy, they still struggle to form sentences or express their thoughts clearly.
Struggling with Social Cues
They often misread social context or situations, catching only a fraction of what’s happening around them.
Short Attention Span
They have trouble staying focused, easily get distracted, and quickly forget simple instructions.
Slow Learning Comprehension
They fall behind their peers in understanding new concepts, making you worry about school readiness.
Ultimately, what your child needs most right now is to build that “Cognitive Foundation.”
But adding another therapy center to your schedule is draining—both mentally and financially.
Now, you can start clinically proven cognitive training at home for just 30 minutes a day with TallerRx. Once the cognitive foundation is set, you’ll see explosive synergy in all their other therapy sessions.
Skip the endless waitlists. Start their progress at home today.

Clinically proven results.
Accelerate your child’s brain development.
Joint clinical trial conducted by Dept. of Pediatrics & Rehabilitation Medicine at a leading University Hospital.
When 3 months of traditional therapy struggles to yield even a single month of progress.
Not a miracle, it’s ‘evidence-based data.’
Your child’s breakthrough is next.
Based on Visual-Motor Integration (VMI) cognitive age data from a 3-month clinical trial conducted by pediatric specialists.
Individual results may vary based on age, initial condition, and training frequency (5 days/week recommended).
💡 3 Keys to Maximizing the Developmental Window
✔ The earlier you start, the greater the impact.
✔ Consistency is crucial: Training 5 days a week drives the most significant changes.
✔ Intervening while symptoms are mild yields the fastest breakthroughs.
🚨 Every day matters. A single day’s delay can compound into a month of setback.
Start today.
Intelligence isn’t about brain cells;
it’s about ‘connections.’
The brain wires new neural pathways every time it receives a new stimulus.
Because these networks fade when left unused, consistent daily stimulation is the absolute key to lasting growth.
Supercharge their neural pathways.
Discover the ‘stimulation difference.’

Real breakthroughs driven by ‘evidence-based data’
“We avoided special ed and made it into a mainstream classroom!”
| Girl 5 (DD)
Her speech delay was so severe we thought special ed was our only option. She just played tallerRx at home for 3 months, and now she’s talking clearly! Her cognitive age jumped over a year ahead of her peers. I’m still in tears of joy that she’s starting a regular elementary school!
“My son was completely stuck, but now he’s finally thriving!”
| Boy 5 (ASD)
After his ASD diagnosis, we dragged him to every therapy possible, but his progress was so slow I was losing hope. We couldn’t even use tallerRx every day because of his other therapy schedules, but the results absolutely blew us away.
“I was totally skeptical, but now she begs to play it!”
| Girl 14 (HSP)
She has an intellectual disability rating from a brain lesion. I didn’t think a tablet game would do much, but she finds tallerRx so fun that she plays it diligently without me ever nagging. It’s honestly incredible how effective this ‘game’ is for her cognitive growth.
Real-life changes pouring in every single day

Frequently Asked Questions
Q. Can a ‘game’ really improve cognitive function and intelligence?
A.
Absolutely. tallerRx is far from a simple entertainment app. It is a ‘Digital Cognitive Intervention Solution’ meticulously designed by professors of Neurology and Rehabilitation Medicine, grounded in Applied Behavior Analysis (ABA) and neuroscience.
Its clinical efficacy is proven by real data—improving cognitive age by an average of 9.3 months after just 3 months of training. These objective results were published in the peer-reviewed medical journal BMC Pediatrics, earning global recognition for its technological excellence.
Q. Is it effective for specific conditions like Borderline Intellectual Functioning, ADHD, or simply easily distracted children?
A.
Yes. tallerRx is a proven solution that delivers outstanding results, particularly in boosting the cognitive abilities of children with Borderline Intellectual Functioning. Furthermore, it is highly recommended for children with ADHD, Autism Spectrum Disorder (ASD), speech and developmental delays, or those who simply struggle with focus and social skills.
While outward symptoms vary, the common underlying cause is often a gap in foundational ‘cognitive domains’ (like working memory and visual perception) needed to process information and understand situations. tallerRx effectively rebuilds this cognitive foundation, helping easily distracted children sit still and focus, while accelerating the processing speed of slower learners.
Q. My child has a speech delay. Can cognitive training actually help with language development?
A.
Absolutely, more than you might imagine. This is because cognition is the ‘vessel’ that holds language.
It’s natural for parents to rush to speech therapy first. However, if your child’s progress feels stagnant despite consistent sessions, it’s time to assess their ‘cognitive vessel’ (the ability to think, process, and understand).
If language is water, cognition is the bowl. What happens if you keep pouring water into a bowl that isn’t properly formed? The child struggles with true contextual communication (pragmatics) and ends up parroting words without meaning, often keeping them stuck in therapy for years.
By using tallerRx to awaken their cognitive domains and build a solid neural framework first, you open the door to true comprehension. Once that cognitive foundation is set, you will witness a remarkable acceleration in speech development and massive synergy with their clinic sessions.
Q. What age group benefits the most? Won’t the games feel too childish for older kids?
A.
tallerRx is widely loved by children from age 3 through early elementary school—a critical window for explosive brain development. We deliberately designed a friendly ‘Animal Forest’ theme so children stay engaged and excited to log in every day without getting bored.
However, don’t let the cute characters fool you; the actual cognitive workout is anything but easy!
Our training logic is deeply rooted in ‘neuroplasticity,’ which rewires the brain regardless of age. In fact, the underlying technology is so profound that it is actively used in university hospitals and rehab centers for adult cognitive rehabilitation and dementia prevention with outstanding results.
Therefore, it is incredibly effective for upper elementary and middle school students who need to build robust ‘cognitive stamina’ (focus and working memory)—the absolute foundation for academic success. The graphics might seem playful, but the intensity of the brain stimulation strictly adapts and scales up as your child grows.
Q. How do we get started? What is the recommended daily training routine?
A.
It’s an incredibly intuitive system—simply download the app on your home tablet, and you can start immediately!
Our highly recommended golden routine is 5 days a week (typically weekdays). Each day, your child just needs to complete the 4 daily missions shown on their calendar, playing each game until they collect all ‘3 stars.’
Based on their daily performance, our AI automatically curates next week’s optimal curriculum. At the end of the week, a detailed progress report is delivered directly to you, so parents can simply sit back, relax, and celebrate their growth.
Q. My child only wants to play their favorite games.
A.
It’s absolutely fine for them to enjoy their favorite games after completing their daily calendar missions (collecting all the stars). However, we strongly advise against skipping the day’s core training to ‘cherry-pick’ only the games they want.
Based on the principle of neuroplasticity, tallerRx provides a strategically designed personalized curriculum that introduces 8 specific games a week. This ensures your child’s brain receives the exact balance of ‘new stimulation’ and ‘consistent repetition’ needed for true internalization. Please guide them to complete their well-rounded daily routine first!
Q. My child refuses to play the harder games. How should parents help?
A.
There is absolutely no need to obsess over high scores or perfect grades! The true goal of this training isn’t getting a high score, but rather ‘accumulating new cognitive stimuli and experiences’ through gameplay.
We actually encourage children to interact with the games in their own creative ways instead of strictly following the rules. When they avoid difficult tasks, rather than forcing a good score, offer gentle hints so they can solve it themselves, or simply encourage them to get familiar with the game environment without the pressure of winning. With consistent exposure, you will soon witness them effortlessly conquering the exact games they initially found too difficult.
Q. We are already attending an in-person therapy clinic. Can we use this in parallel?
A.
Yes, we strongly recommend using them together! You will see the most powerful synergy when in-person clinic sessions are paired with tallerRx’s home training.
Therapy clinics are fantastic, essential spaces for building deep connections with therapists and supporting emotional development. However, for the brain to practically rewire itself (neuroplasticity), it requires both ‘novel stimulation’ and ‘daily repetition.’ A 40-minute session once or twice a week simply lacks the absolute training time required for this change.
Think of tallerRx as your daily ‘cognitive home workout’ that fills the gaps on the days you don’t visit the clinic. Just like doing your daily personal routine after getting Personal Training (PT) at the gym, consistent daily practice with tallerRx will maximize the effectiveness of your clinic sessions.
Q. Can my child play this on a smartphone? What are the recommended device specs and tablet options?
A.
To maximize the effectiveness of ‘visual perception training,’ tallerRx is designed exclusively for tablets. On smaller smartphone screens, the UI will not display properly, making certain games impossible to play. For accurate and effective training, please ensure your child uses a tablet.
✅ Recommended Specs & Quick Self-Check Tip tallerRx is a highly optimized, lightweight app that runs smoothly even on entry-level devices (like the Galaxy Tab A7 Lite or equivalent). However, very old tablets may lack the necessary graphics processing power.
During your 7-day free trial, if you notice the cat disappearing in the ‘Nabi Maze’ game, or characters not rendering properly in ‘Whose Shadow,’ it’s a sign that your device’s specs are too low!
✅ Don’t have a tablet? No need to break the bank! There is absolutely no need to purchase a high-end, expensive tablet just for tallerRx. You can run the app perfectly on budget-friendly tablets (e.g., Amazon Fire HD, Lenovo Tab, or other affordable brands) priced around $100–$150.
Q. Can I cancel my subscription anytime? Do you offer prorated refunds?
A.
Yes, you can easily cancel your auto-renewal at any time!
All payments are securely processed through the native systems of the Google Play Store and Apple App Store. Therefore, cancellations must be managed directly in your device’s [App Store > Profile > Subscriptions] menu, rather than within the tallerRx app. (Even after you cancel, you will retain full access to the program until your current billing cycle ends.)
However, because tallerRx unlocks a customized digital curriculum immediately upon purchase, prorated refunds for partially used periods are generally not provided. (Exceptions such as full refunds within 48 hours of purchase are strictly subject to standard Google/Apple customer service policies.)
This is exactly why we offer a 100% risk-free ‘7-Day Free Trial’ before any charge occurs. Please let your child fully experience the program first, and then make your decision with complete peace of mind! (💡 For detailed legal terms, please refer to the ‘Refund Policy’ at the bottom of the page.)
Q. I want to see if it’s a good fit for my child first. Can we try it for free?
A.
Yes, absolutely! We know all too well that even the best program in the world won’t work if your child isn’t happily engaged.
That’s why tallerRx offers a 7-Day Free Trial to completely remove any financial pressure for parents. During this week, you get unrestricted access to the exact same personalized curriculum and detailed progress reports as a paid subscriber.
For 7 days, watch with your own eyes as your child actively asks for the tablet, builds confidence, and begins to grow!
There is no need to hesitate. Click the blue button below right now and start your child’s amazing cognitive journey for free!
